HYDROCARBONQENGINE FOR IVIIQTOR-VEHICLES.

Patented Sept. 4, 1906.

To 11,17 whom, it may concern:

Be it known that I, JAMES W. PACKARD, a citizen of the United States, residin at Warren, in the county of Trumbull an State of specification.

This invention comprises various improvements in hydrocarbon-engines which are especially intended to adapt this class of engines to motor-vehicles.

n the accompanying drawings, Figure 1 is a side View of a hydrocarbon-engineembodying this invention, parts being broken away. Figs. 2 and 3 are details. Fig. 4 isa plan view, partly in section. Fig. 5 is a view on the line A A of Fig. 4. Fig. 6 is a view on the line B B of Fig. 4.

The engine illustrated in the accompanying drawings is a double-cylinder engine having a single crank, to which both connectingrods are jointed.

One feature of the invention relates to the manner of connecting the cylinders to form a single water jacket. As illustrated, the right-hand cylinder 1 is surrounded by a section of water-jacket 1 and the left-hand cylinder is surrounded by a similar section of Water-jacket 2. water circulation and to set the cylinders close to ether, so that their connections to the oran may be close, the water-jackets 1 2 are 0 en at their inner sides and the inner edges a ut and are fastened by bolts 3. This provides a continuous water-s ace 4 extending about both cylinders an having a sectional form similar to a figure 8. It will be seen that this permits of the cylinders being placed close together without sacrificing any cooling-surface.

A second improvement consists in fitting or telescoping the cylinders into the crankcase in such a manner as to strengthen both and stiffen the connection between them. As shown, each of the cylinders has a cylindrical extension 5, Figs. 1, 4, and 6, which is clamped between the upper section 6 and .the lower section 7 of the crank-case C. The

crank-case is made in two arts dividedalong asubstantially horizontal mepassing through the. crank-shaft, and each of these arts has two semicircular portions at its Ontend In order to facilitate the from the crank-sha adapted to fit closely to the cyunoer extensions 5. The cylinders are also cast with fiangles 8, which fit corresponding flanges 9 on t e front end of the crank-case.

It will be seen that when the flanges 8 and 9 are oolted together and the meeting'flanges 10 11 of the crank-case are also bolted together the crank-case and cylinders become virtually a single piece. The engine is preferably supported from the motor-vehicle frame by a transverse bar 12, extending beneath the flan es 8 9.

Each cylin er is provided with an inletvalve 13 and an exhaust-valve 14. Beneath each valve is a removable plug 15, closing an opening through which the valve may be removed. The inlet and exhaust valves 13 and 14 are located above the explosionchamber 16, and the plugs 15 below said chamber are made adjustable and provided with check-nuts 1-7 for locking them in any desired (position. The object in making the Slugs a justableis to permit of increasin or ecreasing the size of the explosion-sham er, and thereby decreasing or increasing the intensity of the explosion.

The valves 13 and 14 are provided with stems 18, and they are normally closed by springs 19, abutting against heads 20 on said stems. The valvesare positively opened by means of cams 21 on a cam-shaft 22, said cams operating through rollers 23, arms 24, pins 25, and levers 26, said levers bearing at one end upon the pins 25 and at the op osite are carriedby a rock-shaftf28. The levers end u on the valve-stems 18. In or or to 26 which operate the exhaust-valves have bearings which are concentric with shaft 28.

"As shown in Figs. 1 and 3, the rock-shaft 28 is operated by an arm 29 and a link 30, connecting said arm to any suitable operating lever or governor. Thls device provides a very cheap and efficient means for re ulating the ower and speed of the en ine. T e camshaf 22 is driven b suitab e gearing 30 31 g 32. The arms 24 are loosely carried by a rod 33, which has a sliding movement. The sliding movement is intended to permit the cam-rolls 23, which operate the exhaust-valves, to ride upon the cams 34, which are opposite in efl'ect, or sub- Stantially so, to the cams 21. Whenit is desired to reduce the charge in the explosionchamber, the rod 33 is moved over by a lever 35, so that the rollers travel on both cams 21 and 34. This causes the exhaust-valves 14 to open normally during the exhaust-stroke of the piston and then to open again during the compression-stroke sufficiently to let a ortion of the charge escape throu h the exliaust-passages before ignition ta es lace. By this means the power and speed of t e engine can be regulated either by hand or by governor.

, The valve-operatin mechanism herein described forms the su ject-matter of a divisional application, Serial No. 282,646, filed October 13, 1905. I

What I claim, and desire to secure by Letters Patent, is

1. In a hydrocarbon-engine, the combination with two parallel cylinders formed separately, a casing for eaclrcylinder partially surrounding the same, the two casings being joined to form a continuous water-jacket about the two cylinders, of a crank-case formed of two parts suitably connected together, the parts of the crank-case being joined on a lane passing through the axes of the two cy inders, and said cylindersand crank-case having telescoping portions.

2. In a hydrocarbon-engine, the combination with two parallel cylinders formed separately, each cylinder being partially surrounded with acasing at its rear end and having a telescoping portion at its forward end, and said casings being joined to form a continuous water-jacket about the rear ends of the cylinders, of a crank-case formed of two parts which are joined on a plane at right 'angles'to the plane of joining of the said caslngs, the said crank-casebeing adapted to telescope with the said cylinders.

3. In a hydrocarbon-engine, the combination with two parallel cylinders formed separately and connected together, of a crankcase formed of two parts which are joined together on a plane at right angles to the plane of the joining of the cylinders, said cylinders and crank-case having telescoping portions, whereby their connection is strengthened. 4. In a hydrocarbon-engine, the combination of two parallel rately and connected crank-caseformed of two parts connected on a horizontal line, and means for connecting cylinders formedse aon a vertical line wlt a said cylinders andcrank-case, said cylinders and crank-case having telescoping portions, whereby their connection is strengthened.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
